Throttles & Throttle Tubes

Motorcycle Throttles and Throttle Tubes

Throttles and throttle tubes are part of the right-side handlebar controls, transmitting the twist-grip rotation to the system that opens the engine. This category mainly includes replacement throttle tubes and related control components for replacing a damaged, worn, or rough-operating part.

Selection should start with exact compatibility with the motorcycle and the installed throttle assembly. Before buying, check the make, model, year, and version, along with the mounting type, available travel, and the connection method for the throttle cable or cables. Also verify that the length, stops, and housing positions match the removed part.

What to Check Before Choosing

• Compatibility: compare the stated application with the motorcycle’s exact details, not just its engine displacement.
• Configuration: check whether the assembly uses one or more cables and how the throttle tube is secured inside the housing.
• Measurements and mounting: compare the diameter, length, stops, and connection points with the original or replaced component.
• Control operation: after installation, the grip should turn freely, return correctly, and maintain suitable free play according to the motorcycle manufacturer’s instructions.

If the grip, housing, or throttle cables are also replaced, check compatibility across the complete assembly. Incorrect installation can affect operation, so stop checking and inspect the installation if there is any resistance, excessive play, or irregular return.
